【 Abstract 】 The utility model relates to a nanometer antibacterial composite packaging film, which belongs to the technical field of novel structure multi-layer food packaging materials. The purpose of the utility model is to design a nano antibacterial composite packaging film to overcome and solve the barrier property and the resistance. Wet and poor gas barrier properties; nano-antibacterial composite packaging film consists of an inner seal layer, adhesive layer 2,4, middle layer, printing layer five layers, inner seal layer, adhesive layer 2, intermediate layer, adhesive The layer 4 and the printing layer are processed from the inside to the outside, and the nano-antibacterial composite packaging film is used for food packaging, has good physical and mechanical properties, has good stability, heat resistance, toughness and transparency, acid resistance, alkali resistance, Anti-aging, reduced ultraviolet radiation, barrier air intrusion, antibacterial sterilization, can effectively inhibit the growth of bacteria and food spoilage, prevent the external contents of the package contents of the aroma and moisture leakage, to keep the food fresh and original, extended The beneficial effects, advantages and characteristics of the preservation period of the contents of the package.
【Sovereign Items】 1. Nano-antibacterial composite packaging film consisting of five layers: inner seal layer (1), adhesive layer (2), intermediate layer (3), adhesive layer (4), and printing layer (5). The method is characterized in that the inner sealing layer (1), the adhesive layer (2), the intermediate layer (3), the adhesive layer (4) and the printing layer (5) are processed from the inside to the outside by a process of extrusion extrusion. The inner seal layer (1) is an antibacterial layer composed of a polyolefin added with 0.2% to 2% of anatase titanium dioxide, the adhesive layer (2, 4) is composed of low density polyethylene, and the middle layer (3) is High-vacuum aluminized film, printed layer (5) made of biaxially oriented polypropylene.
